LUBRICATIN'G SYSTEM Foa Moron vimrcmce.`

Application led November l8, 1924. Serial No. 747,535,

My' invention relates to lllbricatorsy and more particularly to means for lubricating arts by the use of oil in the crank case'an the motor; and the object is to obtain oil for lubricating pur poses from the motor or crank vcase or other supply source and to hold the oil under pressure for forcing the oil' into the various working parts ywhich need lubricating, and

' object is to utilize the heat from a combustion chamber or cylinder for automatically pre-heating the oil and consequently prearated pum following description an be more particularly pointed out 41n the eating the whole lubricating` systemand at the same time obtaining the necessary pressure to lubricate all workingparts `and to provide means for preventing waste offoil in the working arts.v Other objects and advantages will full explained in the d the invention will Reference is had' to the accompan A drawings which form appart of this app ication.

Fig. 1 is a vside elevation of a portion of a motor equipped with the improved lubricating means. Fig. 2 4is a. similar view but showing also a manually operating pump in combination with the automatic s stem. Fig. 3 is a perspective view,` showing t e ap-V lication of the .devices shown in Fig. 2.- Fig. 4 is a side elevation l-of a manually opfor use where the Amotor is not provided with a motor pressure pump, being a variation from the manually operated pump shown in Fi 2. Fig. 5 is a side elevation of a manua ly operated ump which is a variation from the manua ly operated pumps previously shown. Fig. 6 is a broken sectional view, showing the manner of applying lubricating oil to the vehicle springs and showing means for preventing waste of the oil. v

,Similar characters of reference are used to indicate the same parts throughout the several views.

In the drawings,

`only 'a .suicientpart of a motor vehicle is shown to show the appli- 'cation of the im rovements. An oil reservoir 1 is mounte on the dash board 2. A pipe 3 is connectedto one ofthe combustion chambers of lthe motor 4 and is proj.

- .push the 4vided with an outlet check valve 25.

vided Ywith a stop cock 5 which may be oper'- ated from the instrumentboard b a control 6. The pi e 3 is also provided with a check valve 7 to old the pressure in the reservoir 1. Means are provided for filling the reservoir 1 with lubricating material. i A pi e 8 is connected to theil pressurepump o the motor and extends'to the oil gagel)v and a three-way valve' 10 is provided for this pipe and the valve 10 is-connected lo the reser-.

voir`1'. To'fill the tank 1, turn the valve 10 one 'quarter turn.' This will cut .the oil oil' from the pressure 4ga e 9 and openl the .I

port to the tank 1A so t at oil may come through the pipe 8'to the tank 1. `llihen the tank is filled, turn thewvalve 10 back a (pillarter turn.- `vThis willlet' the oil back to t e pressure gage 9. To put the oil in tank 1, open cock 5 so` t at pressure will come from the combustion chamber. A

distribution pipe 11 isfconnected to the tank 1 and to the main Vdistributing pipe 12 and is provided w' h connected-.to i various working parts of the vehicle. 5 shows pi es 14 and 15 for such purposes.

Fig. 2 s ows a manually operatedpump 16v which is provided with a iston 17 yfor filling the` pump ortank 1 with air, that is', air is pumped into the tank 1 to obtain pressure on the oil therein, so that pressure may e pipe 12 to extend to the .be obtained without obtaining ressure from ressure on a cock '13. Pipes may be Fig.

the engine. vThe advantage ist at the worky ing parts of the vehicle may be lubricated without starting the-motor.

The variation shown in Fig. 4 is provided with a tank 18 which is providedwith a piston19. TheA tank 18 is connected by a pipe 20 with athree-way valve 21. A pipe 22 is connected to the three-way valve 21 and to the crank case of the motori The valve 21 is controlled by the rod 23. For umping oil out of the crank case, pull on t e piston 19. This Awill fill the pump reservoir 18. To force the oil vout through the' workin parts, turn the cock 21 one quarter turn an iston 19 inwardly. This will drive the oil out of pump 18 through the pipIe 11.

he variation shown in Fig. 5 comprises a combination oil andair pump. The valve connection is dil'erent from that shown in` Fig. 4. The pipe 2O is rovided with an inlet check valve 24 and t e pipe, 11 is roen the valve 21 is turned -tocommunicate 'the Y pistonv 19 will fill thepump 18. To force' pipe 11. To usethe K pump, .turn the valve crank case through pipe 22, a pull on the the oil out through the pipe 11, force the pist-on 19 inwardly. The check valve 24 will be closed and the checkv valve 25 will be opened and the oil will be forced out through pump 18 f or an air 1 one qua-rter, turn` The ump can then be filled with air bypulling 51e piston 19 outwardly. Pressure can then be Ihad on the oil that may be in the' system of distribution pipes by pressing the piston 194 back inwardly. I I

Fig. 6 illustrates how the Working parts may be protected. The springs 2,6 mai be covered with .felt 27 to serve as a wic or oil distributer for the springs.l .One of the' distribution pipes 14 is laid on the felt 27 and perforated to let oil out. on the felt. Then the springs and felt are provided with a cover 28*l This construction and arrangement will keep the dust and dirt out and will keep the springs lubricated.

Various other changes'in the construction ement of the several parts may be out departing from my inven=v and arran made wit tion. b

What Iclaim, is,- 1. In a motor vehicle provided with an operating motor and working parts of a motor vehicle; means for lubricating said working'parts comprising a container and a gage associated with said container, means or supplylng said container with a lubricant includin a pipe extending from 'the oil pump o 'the motor to saidvcontainer and to said gage,. means for controlling the flow of lubricant to said'container vand gag?,

`wor f pipes forv delivering lubricant to said mg parts, and means for utilizing the pressure and heat of the combustion chamber of the motor for heating'lubricant for" all the working arts and for controlling the pressure on t e' lubricant in said container con- Vsisting'of a pipe connected to said 'combustion chamber and to said container and a cock for said pipe and means for use of the operator to actuate said cockfrom. hisseat.

2..In a motorv vehicle operating. motor and Wor ing parts of a .motor vehicle; means-for' lubricating said working parts comprising a container and gage therefor, means for vsu plying said con-y tainer with a lubricant inc uding a pipe-extendingv from the oil pump of the motor to rovided with an the container and its gage, means^ for uti- `1izing pressure from a 4combustion chamber of said motor for forcing -lubricant from said 1 container including a pipe leading from the combustion chamber to the container and a meansifor controllingv the passage of the pressure to the container, ipes fo'r deliverf ing the lubricant from sai container to said workingparts, and means for conserving the lubricant about said working parts.

In testimony whereof, I set my hand, this 25th day of October, 1924. v MARION W. SULLINS.
